Abstract
Core-shell particles were obtained via the layer-by-layer assembly of oppositely charged polyelectrolytes on the colloidal templates. Not only polyelectrolytes but also a number of materials having multivalent charge are applicable for the layer-by-layer assembly technique. Heteropolyacids also have multivalent charge and comprise a structurally diverse class of inorganic transition metal oxygen clusters which owing to their unique electronic properties hold promise for a host of technological applications such as heterogeneous catalysts, proton conductors, etc. In this study, hybrid core-shell particles formed with multilayer of polyelectrolytes and heteropolyacids were prepared via the layer-by-layer assembly technique. The obtained particles were characterized by FT-IR, electrophoretic mobility, and electron microscope. In addition, their assemblage property was also investigated.
